Hi,
it seems that you've got a very old version of the Premium/Projects module. It's been removed from the core package some time ago. Now you should register your installation and obtain a free license for this module and download a newer version from the store.
Open modules administration and store -> register -> download projects module. But first check your file permissions. Module directory (and all subdirectories and files) has to be writable by the http server user.
Regards,
Adam
